Problems solved by technology

Therefore, the safe operation of the on-board computer directly affects the driving safety, and if there is a small problem, it will lead to serious consequences.
[0003] At present, the on-board computers in domestic and foreign rail transit train operation control system products are mainly two-by-two or three-by-two, so that the safety level can be achieved, but the whole system is too large, and most of them need two to three boards to work together. Complete the same function, so the design of the hardware system is complicated to build, the overall system is inconvenient to transplant, the product integration is low, and the miniaturization design is difficult to achieve, and it cannot be satisfied when the product requires high integration and miniaturization design, and it brings design costs. , The problem of high maintenance cost

Embodiment Construction

[0031] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0032] At present, there are two CCU units (main and standby) in each train driver’s cab in the rail transit industry. There are two driver’s cabs in one car. Under normal circumstances, only the main CCU unit works. The two main CCU units communicate with each other and receive each other in real time. Working status code, to judge whether the other party is working normally, if it is judged that the other party’s status feedback is abnormal, send a command to start the other party’s standby CCU unit to take over the work.

[0033] At present, the on-board computers in domestic and foreign ra...

Abstract

The invention, which belongs to the technical field of rail transit and industrial control, relates to a vehicle-mounted computing system for rail transit operation control. The system comprises a first processor, a second processor, an FPGA programmable device and an ARM processor. The first processor and the second processor are respectively connected with the FPGA programmable device; and the ARM processor is integrated in the FPGA programmable device. The system further comprises an SSD memory hard disk and an ISA bus. The SSD memory hard disk and the ISA bus are respectively connected with the ARM processor, and the ISA bus is connected with the ARM processor. With the vehicle-mounted computing system, problems that the existing rail transit train operation control system is complex in construction, inconvenient to transplant, low in product integration degree, difficult to achieve miniaturization design, high in product requirement integration degree and incapable of meeting theminiaturization design, and design cost and maintenance cost are too high are solved.

Description

technical field [0001] The invention relates to the technical field of rail transit and industrial control, in particular to a vehicle-mounted computing system for rail transit operation control. Background technique [0002] In recent years, the rail transit industry has developed rapidly. The train operation control system in rail transit is the main equipment to control train operation, ensure railway traffic safety, and improve transportation efficiency. The on-board computer equipment is a key part of the train control system, which is mainly responsible for monitoring trains. The running speed of the train, the starting state and running state of each equipment of the train. Process the calculation work generated during the operation, save the operation data and status in real time according to the application program, and reflect the data and status to the ground monitoring station in real time. The ground monitoring station will analyze the data after receiving the d...
